Velocity and temperature derivatives were obtained at a height of 4 m in the atmospheric surface layer above land. With the assumption of local isotropy, these measurements are used to obtain some statistics of the turbulent energy and scalar dissipation fields. These statistics include the variances of the logarithms of the scalar and velocity dissipation fields and the correlation between these logarithms. When used in conjunction with the hypotheses for fluctuations in turbulent dissipation rates of Obukhov and Kolmogorov, the statistics suggest that the dependence of the flatness factor of temperature derivative on the turbulent Rynolds number R, is not as large as that which had been previously reported in the literature. The experimental data indicate a RF5 dependence for the kurtosis of the temperature derivative and a Rt " variation for the strain rate-scalar dissipation correlation. regard to the statistics of E, and x, were analogous to the assumed properties of F, in Kolmogorov's third hypothesis. The probability density functions of Ed and X~ were assumed to be lognormal while their joint probability density function was bivariate Boundary-Layer Meteorology 18 (1980) 399-410.
